Introduction to the study of light dispersion

In keeping with the mission of scientific researchers, and particularly that of popularizing results in the field of geometrical optics, which is a part of physics.We have chosen the topic "Introduction to the study of light dispersion" in order to help scientific researchers, learners and teachers in this field.Light, which is a physical agent capable of impressing the retina of the eye, would be dispersed by passing through the prism, which is a transparent medium.
